Top Factors for Ranking the Best Mobile Slot Apps

A lot of research and testing goes into our list of suggestions of where to play online slot machines. We consider a wide range of factors and look very closely at how a mobile gambling app performs in various key areas.

Every single factor we consider is important in its own way, but there are certain factors that are especially significant. The following is a list of the top factors we look at when ranking the best mobile slot apps.

  • Licensing and reputation
  • Slot game selection
  • Deposits and withdrawals

Licensing and Reputation

The best mobile slots apps are those that are operated by companies that are licensed in reputable jurisdictions and that have a good reputation and history in the online gambling industry as a whole. When looking at this, we start with their license and look to answer the following questions.

  • Where is their online gambling license from?
  • Is this a reputable casino licensing jurisdiction?
  • How long have they had this license?
  • Has this license ever fallen out of good standing?

We only recommend real money slot machine apps that are licensed from reputable regulatory jurisdictions, and we generally will not recommend an operator that has ever had their license fall out of good standing unless there was some kind of atypical circumstance.

How long the site has been around and how long they have had their gambling license are questions that are a bit less important. The reason for this is that there are operating groups that run several sites, and those sites will generally all run under the same licensing jurisdiction.

If the company running the show is reputable along these lines, then we see no reason to be alarmed if they open another site with a mobile online slots app that is newer than the others.

Mobile Slot Selection

In the mobile slot sector of the online casino industry, there are two main factors to consider on the topic of game selection: quality and quantity.

Thankfully, there’s enough competition and enough casino sites running with mobile options that there are plenty of choices that cover both sides of this particular coin.

When we are researching and selecting apps for inclusion in our rankings, what we’re looking for in terms of slot machine selection is quality first and quantity second.

Our logic on this is that it doesn’t matter if a mobile app for slots has thousands of games available if all of them are terrible.

It doesn’t matter what slot games and slot types you prefer. There are high-quality games in all genres, and that’s what we aim to recommend no matter which of our mobile slot machine apps you pick.

From there, we look at the number of online slots available. This is largely a function of the software providers that are used for the particular app in question. Some providers have tons of games available, and others do not.

If you’re looking for mobile slots from a specific provider like Microgaming, Net Entertainment, or Betsoft, then you’ll want to make sure that you pick out those options, but outside of that, all we care about is that there are plenty of high-end titles to pick from.

Deposit and Withdrawal Options

With real money slot apps, you’ll need ways to send money to your account and ways to receive your funds from your account. This is mainly done with a handful of available groups of options, such as credit and debit cards, electronic wallets, or cryptocurrecies.

We only ever recommend real money gambling apps that provide a choice of reputable payment methods for your deposits and withdrawals.

Our ideal situation would be for each player to have at least two ways to deposit and two ways to cash out so that if there’s a technical issue with one method, slots players will always have a backup available.

This is because we know what it’s like to not be able to get your winnings after requesting a withdrawal. Therefore, we only include the top mobile slot app options that have quick withdrawals and a good reputation for paying when they are supposed to.

How to Pick a Real Money Slot Machine App

Picking out a real money slots app that works well for you is critical if you want to have a good online gambling experience. To do this, you can’t just rely on what has worked for other people because they aren’t necessarily looking for the same things as you.

We recognize that players are individuals, and we’re going to show you how to figure out where to play mobile slots while keeping that in mind. These are also factors that we consider when ranking the best apps for playing real money slots.

Mobile Slot Bonus Options and Promotions

Right out of the gate, you’ll want to pay attention to the types of bonuses and promotions that are available at each of the apps . Some of them will give you a strong first-deposit bonus without much coming after that, and others will give you a more modest offer on your initial deposits while giving you more value spread out over the length of your time there.

There is no one-size-fits-all option for online gambling bonuses and promotions. You have to pick what will work for you based on your own stakes and how much you anticipate playing.

There are a handful of promotion types that you’ll see often. Once you know what they are, it’s usually straightforward to know which bonus types will be the best fit for you, and you can narrow down your choice from our given slot app recommendations accordingly.

First-Deposit Bonuses
These give a sizable amount of value on your first deposit, but they can only be used once. Several can be taken advantage of if you plan to jump around to different casino apps.
Reload Bonuses
You can get these occasionally or on a regular basis depending on the app. These are best for players who plan to make small or medium deposits on a somewhat regular basis.
Tournaments and Leaderboard Events
Players earn points for their play in these events that then give them chances to win prizes. These work best when you’re interested in putting in a lot of time to their mobile slot play.
No-Deposit Bonuses and Free Chips
No deposit bonuses can be used to try out slot games before you make your own deposit with real chances to win real money prizes.

The method we recommend is deciding which two or three of the above bonus types appeal to you the most and then narrowing down your options based on the mobile slot apps that give you the most value through those picks.

Desktop Play Integration

One of the cool things about picking out where to play mobile slot machines is that it’s not always about the mobile side of things, strictly speaking. This is because many of our recommendations give you the ability to play from the same account with the same balance on a computer as well as through the app.

If you’ll want to transition back and forth between the desktop and mobile options, then you’ll need to make sure that your pick allows for that. This is usually the case when you’re playing with an online casino that uses a mobile web app for slots instead of a native app that downloads and installs directly to your smartphone or tablet.

Some players won’t care about this so much, but others will, and that difference can be pretty critical if you’re interested in desktop play. Mobile slots have taken over a significant amount of the overall play time from their desktop-oriented cousins, but many people still want the options to do both.

Customer Service Options

Whenever there’s real money involved with anything on the internet, you want to be able to contact a support team member if something isn’t working the way that it’s supposed to. This is no different when playing on real money slot apps, so if anything goes wrong or isn’t working correctly, then you’ll want to be able to speak with someone.

Virtually all of the best slot apps have 24/7 customer service, so time of day isn’t that much of an issue. However, choosing how you actually go about having that conversation with the customer service team is a whole different thing. There are a number of different options that you can find at some of the best slots apps.

  • Email
  • Live messenger chat
  • Telephone
  • SMS/Text Messaging
  • WhatsApp
  • Skype

You may see some additional contact methods, but these six options are the ones you’ll encounter the most, with the first three being particularly common. Not all online slot apps will have the same support options, so you’ll want to pick out which contact method or methods from this list appeals to you the most and narrow your slot app search along those lines. Focusing on the first three options will give you the best results as well.

The Types of Mobile Slots Apps

Players will find that there are a lot of different types of slot machine apps for smartphones and tablets. Because so many of them work in different ways and provide different things, it can be tricky to know which way is up, so to speak.

In what follows, we’re going to show you the types of casino slot apps that are available, what you can expect from each, and which are the best options for the vast majority of players.

Different Kinds of Free Play Slot Apps

If you search your phone or tablet’s app store for slots, you’ll almost exclusively see options for free play games because options for betting with real money generally aren’t always allowed to be listed in app stores. This creates a dynamic where there are two ways that slots developers can make money off of you downloading the app and playing.

  • You pay for the apps up front, which means that you’re paying to play free money slot games
  • You view ads while you play, which is annoying and breaks up your sessions in a way that is not enjoyable

Neither of these options is particularly nice, but there’s a third option that does not involve your app store. You can instead check out our list of the best slot apps provided earlier.

All of our recommended mobile apps for slots will give you unlimited time getting in on the action, even with play money if that’s what you prefer, with no ads and no cost to you.

It’s also worth pointing out that the games with these recommended apps will usually be higher-quality than what you’ll find with the free slot apps in your app stores. They have been developed by the best online casino software developers in the world instead of by a general game company that decided to make a few slots.

Native Downloads vs. Web-Based Options

The way that online slots games run on your mobile device can also vary a bit, and there are two primary options. The first option is called a native app, and that means it was designed to be downloaded to your smartphone or tablet like most other apps.

  • Pros: Native slot apps can be launched in one tap, and they require no significant loading times after they have been installed
  • Cons: The game selection is limited because all of the titles have to be stored directly on your device, and updates have to be installed often

The second option is web-based and runs through your browser. This is the choice used by most of the best slot machine app developers because it offers the highest level of game selection with no download required upfront.

  • Pros: Web-based slot apps can offer access to thousands of games, and there is no time wasted with updates
  • Cons: You will have to take a few moments the first time a game loads on your device, and you’ll be required to log in each time you want to play

Web-based slots apps are generally the way to go for a number of reasons, and all of the sites we recommend the most use a flexible app that can be used on a variety of devices no matter the screen size or operating system you use.

Slots App FAQ

More people play slots on mobile than any other type of casino game. Along these lines, it’s not surprising that a lot of players have a lot of questions, and that means that some of the same types of questions will come up frequently.

Here we have compiled some of the most common questions from players who want to get started with an app for playing slots on their smartphone or tablet.

Can I manage my slots account from my mobile device?

Players can access and manage all of their relevant account information from the same device that they play from. This means that, for all of our recommended apps at least, you don’t need a computer for any part of the experience.

You’ll be able to manage aspects of your account like your personal information, deposit details, bonus terms, and so on from your smartphone or tablet.

Do these mobile slots work well on devices with small screens?

Yes. The top mobile slot apps have been designed to function well on small screens like smartphones and tablets.

A common concern that many players have, especially when they are first introduced to mobile online slots, is that the screen of their smartphone will be too small for them to enjoy the games. The controls on mobile slots aren’t handled in the same way as in a desktop-based game.

When you’re using a touchscreen device instead of using a mouse, you need a different distribution of screen real estate to interact with a game. This is because you’re using your finger or a stylus, both of which take up a lot of room, on a screen that isn’t as large as a computer screen.

The best slot apps get around this limitation by using a different style of controls. Larger buttons that are often transparent are overlaid over the grid of symbols, and they’ll usually disappear once the reels start spinning so that you can better see the action.

Controls for betting, number of paylines, and so on are also included in a second screen for most of the top mobile slots apps, so they don’t interfere with your play either.

Can I play at more than one mobile slots site at one time?

It’s completely possible to have accounts with multiple slot apps. There are no rules against it or any problems along those lines. However, on most smartphones and tablets, you usually can’t have more than one active app on your screen at once.

So while you can have active accounts at all of the best slots apps if you want, and while you can even have the apps running at the same time, you most likely won’t be able to actively play with both at the same time.


We’ve listed out the best slot apps available along with how to pick out which one will be the best fit for you as an individual. Being able to play your favorite online slot machines while you’re out and about on your mobile device is a lot of fun, especially since you can access thousands of the top slot games in the world no matter where you are.

With new games coming out all the time, virtually all of which are mobile-compatible, players never have to worry about running out of new slots to try.
